ガラスがある。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to wear-resistant functional glasses. Functional glass is glass that has an optical thin film formed on its surface, and has functions such as antireflection and increased reflection. Examples of functional glass include heat ray reflective glass.

Can be used for items that are easily exposed to harsh conditions.

択の自由度を増すことができる。 Conventionally, functional glass has been manufactured by forming an optical thin film on the surface of a glass substrate using physical or chemical surface treatment techniques. For example, when used in automobile window glass, so-called tempered glass, which is tempered in advance by heating and air cooling, is generally used as the glass substrate to increase its strength against mechanical and thermal impact forces. On the other hand, since optical thin films generally have poor abrasion resistance against mechanical frictional forces, they have been treated with abrasion-resistant coating, for example, to improve their abrasion resistance. The optical thin film herein refers to a thin film formed on the surface of a substrate such as glass for the purpose of preventing reflection, increasing reflection, etc. on the surface of the substrate, and utilizes the interference effect of light. An optical thin film may be formed of only one layer, but it may also be formed as a so-called multilayer film in which high refractive index materials and low refractive index materials are alternately laminated. When the optical thin film is formed as a multilayer film, the antireflection effect and the reflection increasing effect can be further enhanced. Furthermore, it is possible to widen the wavelength range of light that causes reflection prevention or increased reflection, and to increase the degree of freedom in selecting the material forming the thin film in relation to its refractive index.

造に消費するエネルギーも大きかつた。 However, the conventional functional glass described above did not have sufficient wear resistance. Therefore, it was somewhat difficult to use it for automobile window glass, etc. In addition, in the conventional manufacturing method described above, the process is complicated and the time required for manufacturing is high because the glass strengthening process and the process to improve the abrasion resistance of the optical thin film are performed separately. It took a long time and consumed a lot of energy to manufacture.

上記目的に沿い、本発明者等は研究を重ねた結

て形成される層をいう。 First, the wear resistance of an optical multilayer thin film can be improved by forming a diffusion layer at the boundary between each thin film layer constituting the multilayer thin film. The diffusion layer refers to a layer formed by mutually diffusing molecules in each thin film layer into different thin film layers through the interface between the thin film layers of the multilayer thin film.

On the other hand, the temperature at which the glass is heated during the heating and air-cooling strengthening treatment of the glass is a temperature close to the softening temperature range of the glass, which is generally about 650°C to 700°C. Therefore, the heating and air cooling strengthening treatment of the glass and the formation of the diffusion layer can be performed at the same temperature.

In the abrasive functional glass, the high refractive index material is at least one of zirconia (ZrO 2 ) and titanium oxide (TiO 2 ), and the low refractive index material is silicon dioxide (SiO 2 ) and alumina (Al). 2 O 3 ), and the high refractive index material and the low refractive index material form a diffusion layer that is mutually diffused from the interface between the two near the interface between the high refractive index material and the low refractive index material. It is a wear-resistant functional glass.

They are formed by mutual diffusion into each thin film. Such a diffusion layer can be formed by heating the optical multilayer thin film to about 450° C. or higher, as described above.

するためである。 The wear-resistant functional glass of the present invention can also be produced by forming an optical thin film on tempered glass and then heating it to form a diffusion layer.
However, it can also be manufactured by performing heating air-cooling strengthening treatment to improve the strength of the glass and forming a diffusion layer to improve the abrasion resistance of the optical thin film in the same process. In that case, the heating temperature is approximately 650°C to 700°C. The formation of a diffusion layer in an optical thin film is possible by heating it to about 450°C or higher, but heating and air-cooling strengthening treatment to increase the strength of glass is done at 700°C, which is the softening point temperature range of glass. This is because it is necessary to heat it to close to ℃. Further, in order to obtain sufficient strength of the glass, it is necessary to rapidly cool the glass after the heating, and it is desirable that the cooling rate is faster than about 100° C./sec. Heating is performed in a heating furnace, and cooling is performed by evenly blowing air onto both surfaces of the heated glass. Compressive stress is generated on the surface of the glass by such heating and air-cooling strengthening treatment, and the strength against thermal and mechanical shocks is strengthened to about 3 to 5 times that of ordinary glass. The reason why the compressive stress is generated is that the surface of the glass is first solidified by the cooling.

製造することができる。 When the functional glass of the present invention is manufactured by such a manufacturing method, the heating and air cooling strengthening treatment of the glass and the formation of a diffusion layer for improving wear resistance can be performed in the same process, which reduces energy consumption. It can be produced in small quantities and in a short time. Furthermore, since heat treatment is only required once throughout the entire process, it is possible to produce smooth functional glass with less distortion of the glass surface due to heating.

Further, FIG. 3 is a characteristic diagram showing the relationship between the heat treatment temperature in the above manufacturing method and the haze value and degree of strengthening of the heat ray reflective glass of this example manufactured by the method. As shown in FIG. 1, the heat ray reflective glass of this embodiment is produced by forming an optical multilayer thin film 2 on a non-strengthened glass substrate 10 by vacuum evaporation, and then heating the film to about 650°C to 700°C for 15 minutes. It was produced by heating for a minute and then rapidly cooling to 50°C at a cooling rate of 150°C/sec. Cooling was performed by blowing air evenly onto both sides of the heated glass in air.

によつて構成した。 As shown in FIG. 2a, the optical multilayer thin film 2 has a structure in which thin film layers 21 of zirconia, which is a high refractive index material, and thin film layers 22, which are alumina, which is a low refractive index material, are alternately laminated. Furthermore, a diffusion layer 23 is interposed near the boundary between the cerium oxide thin film layer and the silicon oxide thin film layer, as shown in FIG. 2b.
Zirconia thin film layer 21 and alumina thin film layer 2
The optical film thickness nd (n is the refractive index, d is the film thickness) of No. 2 is 1/4 of the wavelength λ of the infrared rays to be reflected. For example, if you want the optical multilayer thin film 2 to have a reflection increasing function for infrared rays with a wavelength of about 1000 nm, the thickness d of the zirconia thin film layer 21 should be about 105 nm,
The thickness d of the alumina thin film layer 22 is 155 nm.
Note that the thickness of the diffusion layer 23 is 3 to 10 nm. A multilayer thin film having such a structure was constructed by controlling the quantity and time of the substance to be evaporated in a vacuum evaporation method.

る。 Due to the heating, alumina and zirconia mutually diffused through the respective interfaces as shown in FIG. 2b. In addition, because the surface is solidified first by the heating and rapid cooling, a stable compressive stress layer is formed, and the glass has increased strength against mechanical and thermal impact forces. In order to find the optimum temperature for the heat treatment, the above experiments were conducted at each temperature. The results were as shown in the graph shown in FIG. In other words, the haze value, which indicates the degree of wear resistance, is 450.
It is greatly improved by heat treatment at temperatures above °C. On the other hand, the value indicating the degree of strengthening of glass is improved by heat treatment at a temperature of 650°C or higher. Therefore, when both strengthening the glass and improving wear resistance are to be achieved by one heating, the optimal temperature for the heat treatment is about 650°C to 700°C.

It is characterized by the presence of a diffusion layer at the boundary between the silicon thin film and the cerium oxide thin film. Further, the wear-resistant functional glass of the present invention can be manufactured by performing the glass strengthening treatment and the formation of the diffusion layer in the same heat treatment process.

Therefore, it is particularly useful for products that are used outdoors and are easily exposed to harsh conditions, such as automobile window glasses. Further, the manufacturing method detailed in the Examples can strengthen the glass and improve the wear resistance of the multilayer film by a single heat treatment, so the entire process is shortened and the energy consumption is also low. Furthermore, since only one heat treatment is required, there is less distortion of the glass plate.
